Instrument cluster voltage limiter.

What you really want is 23, but 23 is not a standard resistor, and you want enough wattage that it doesn't heat up and change. They are cheap. A package of 4 is easy to get. Last time I was there they had nothing close to 23 ohms singally. Sorta like buying one egg.

You cannot look them up online, either. Radio Shack's idea of a "catalog" is "sort by price" or "best seller" How stupid is that.
